Mobley Moves to Dump By Rood Braker With the ecology buffs screaming about noise pollution and land for racing getting harder and harder to find, the Enduro Run is coming back into popularity. As further evidence, hundreds of thousands of 'Enduro' model motorcycles have been sold by Yamaha. Kawasaki and Suzuki. While it is true that many of these will never see an Enduro Run. it provides many riders with the legal equipment to ride on one of these runs should he decide to go. While many riders just go along for the ride, the ones who try to make it without any advance preparation usually find themselves waiting for the clean·up crew. The next few articles will show some of the things that were done to prepare a Kawasaki 350cc Bighorn for the National championship 500 mile Greenhorn Enduro. This is a two-day event, and with just a few nights of preparation, the Kawasaki made it through the whole run without having to have any adjustments or work done to it at all. The first things to worry about 'are items which concern the riders safety. these are the things that should be checked no matter what else is forgotten. , 3.) A little bit of safety wire wrapped aroUiid each set of spokes at the point where they cross each other as shown could save you a lot of trouble and woe. This will not only add a little strength to the wheel and help it resist flex upon impact. but should you possibly break off a spo'ke it will retain it in position instead of letting it flop around to possibly get caught in something like the rear chain. Do this on both front and rear wheels. 1.) As you are checking the machine over prior to the run, you wHI naturally check to see that the rear chain is adjusted correctly. When you have finished adjusting the rear chain, do not neglect to install new cotter keys in the axle shaft and in the rear brake plate anchor arm bolt as shown. Should either of these nuts come adrift, it could cause a bad spill, so be sure to check them. If your axle does not have provisions for a coner key, it would be a good idea to drill it so that one could be inserted. ~ " for handling and thus for safety. While most of the macfiines come with pretty chrome springs exposed on their shocks, and granted they do look racey and tough, but let's face it, being exposed so you can see them also means that the seal for the rear shock is also exposed. If you are riding in sandy country, 'the rear wheel throws dirt and grit right onto the rear shocks and it won't be long before this grit has eaten away the seals and you have lost your shock oil and instead'of rear shocks, you have rear springs (at least they are pretty chrome springs). To help save them, every time you go out onto the dirt, make up an economical cover like shown here out of an old piece of inner tube. This will keep the dirt and grit out of the shocks and if you also ride the machine to work or school during the week, they can be cut off on Monday morning and a new pair made up the next time you are going out into the dirt. whatever, some type of bracket to give a little stability to the front forks can help when the going gets rough and you might start riding over your head. One of these braces might mean the difference between staying on the wheels or crashing should you happen to land on the front wheel. The fancy aluminium ones like shown here are expensive, but they do the job. The prime thing to remember ~hen installing one of these is to make sure it fits up to the legs, if it has to be drawn out to the fork le~ to fit, it is not right for your forks.

While Bob did not ride it himself, some of Northern California's f'mest moto·Xers did, including Bob Bowers, teaming with John PauJ on a 250 CZ for the overall win for Charley Brown Cycles. Martin Towne and Bill Grossi, Jr. teamed on another 250 CZ that finished second on the same lap. These two teams were the only ones that completed 53 laps. The teams of Achteburg/Harvey, Ronssc/Guzzi and Legge/Edward were all one lap down. Bowers led from the Le Mans start and didn't give it up more than once. Towne had the lead for a few laps when Bowers and Paul were changing riders and the team of Williams/Huffman held down second and third for awhile until a fiat tire finally stopped them. Finishing out the eight trophies were two Pen tons, Watts {Trotter, 6th and Meyer/Ronscc, 7 tho The final trophy went to the team of Christensen and Christensen on a 250 Husky. They had completed 48 laps, only five off the pace. Odd balls racing in this Marathon' included San Francisco Indoor Champion Mike Yarn teamed up with young Mike Kenyon on this writer's 360cc EI Montadero Bultaco, normally seen at Enduros. It held up for the distance with nothing more than the addition of gasoline and oil on the chain. Kenyon fell numerous times that caused a leak in the tank, but that wasn't found until the next morning when the dirt was washed off. The only other thing to be done was to bend the c1ip·ons back to some semblance of straigh Iness. Clip-ons, you remark? Right on, brother. Next year, who knows? This Bultaco was the only one entered and finished tenth in front of the only four storke, a Honda 90 with the team of Langston/Soderling in control. Steve Langston spent much of the time taking broken parts off the bike, but it ran just the same and they completed 46 laps. (Results on page 48) • 4.)

A Marathon is defined in a variety of ways including the marathon that is seen at the Olympics. This two-hour marathon took place at the Santa Cruz municipal dump. The first marathon motorcycle race by Lynn Mobley took place at the very beautiful De Laveaga Park, now a golf course. Such is the way of politics. Those that attended the Inter·Am in 1969 and saw Joel Robert do his thing can consider themselves lucky that they saw somethinl( as beautiful as that, for th ose parks are certainly hard to find. But, having any space to ride on is better than, say, living in San Mateo County, where there is no motorcycle riding area. . The course was set up by Bob Grossi. He walked around sticking poles in the grounds and came up with a tough motocross track that is quite dry with hoop·de·dos everywhere and two fairly fast straigh taways.
